OLOF WIKEN, OF MILWAUKEE, WISCONSIN,

BOGK, OF MILWAUKEE, WISCONSIN ASSIG-NOR OF ONE-HALF '10 FREDERICK BAG FILLER.

Application filed April 5,

This invention relates to improvements in bag fillers.

In filling bags with finely powdered material which flows rapidly when poured, it has been'found difficult heretofore, to check the flow when the bag has been filled to the proper level. Devices employing valves or other internal shut-off mechanism have provento be unsatisfactory as they do not provide a positive check, but allow some material to leak through. Furthermore, these devices are easily clogged up.

It is one of the objects of this invention to overcome the above-mentioned objections and to provide a bag filler which has means for stopping the flow instantaneously at any desired time.

It is a further object of thisinvention to provide a bag filler in which there is no internal mechanism which can become clogged.

It is a further object of this invention to provide a bag filler which has means for positively checking the flow "of" material without permitting any to leak through.

It is a further object of this invention to provide a bag filler which is very easy to manipulate.

It is a further object of this invention to provide a bag filler which is simple in construction, eflicient in operation, and well adapted for the purpose described.

With the above and other objects in view, the invention consists of the improved bag filler and all its parts and combinations, as

V set forth in the claims, and all equivalents thereof.

In the accompanying drawings, in which the same reference characters designate the same parts in all of the views:

Fig. 1 is a front elevation of the bag filler in the closed position, part being broken away;

Fig. 2 is a similar view showing the open position; and

Fig. 3 is a side view of the device in the closed position, part being broken away.

Referring to the drawings, the numeral 5 designates a hopper to the lower end of which a tubular discharge member 6, constructed .of sheet metal or other suitable material, is

connected. On the lower end of the member 6, a tubular member 7 of compressible material, such as a section of an inner tube, is secured by a clamp 8. A

A bolt 9, extending through the tubular member 6 has a pair of tongs 1O pivoted together at. their inner ends on each of its end portions. The outer ends of the tongs are formed with flanges 11. Connectedto the flanges of two opposite tongs is a channel strip 12, and to the flanges'of the other two tongs is a 'T-strip 13. i

A bolt 14, extending through the lower portion'of a tubular member 6, has one end'of a U-shaped lever member secured to each of its end portions. The lever memberhas each of its ends cut obliquely as at 16, and within the curved portion of the lever, acounterweight 17 is' secured, to normally cause the lever to assume the position shown in Figs. 1 and 3. A handle'18 is mounted between a pair of spaced-apart extensions 19.

Lower links 20 connect the ends of the lever with the pair of tongs carrying the T-strip 13, and upper links 21 connect the ends of the lever at, the shorter upper side to the pair of tongs carrying the channel strip 12'.

The operation of the: device is as follows: The bag to be filled is placed beneath the compressible tubular member 7 and the operator raises the lever 15 to the position shown in F ig.2. This causes the tongs to release" their grip upon the flexible member and allows material in the hopper 5':to flow into the bag. When the bag is filled to the proper level, the operator releases the lever, and the latter, due to the weight 17 will drop to the'position shown in Figs. land 3, causing the tongs to come together, thus instantaneously and positively stopping the flow of material regardless of how fine the material may be, or of how heavy a load there may be in the hopper. The two strips 12 and 13 grip the flexible member very securely between them, preventing all chance of leakage.

From the foregoing description, it may be seen that the improved bag :filler is very simple in construction, is inexpensive to manufacture, and is well adaptedfor the purpose. described. 1 y

What I claim is:

1. A bag filler comprising a hopper having a discharge opening, material discharging means having a portion constructed of compressible material connected to said opening, tongs in pivotal connection with saidhopper for gripping said compressible portion to check the flow of material therefrom, and a U-shaped lever in pivotal connection with said hopper for operating said tongs.

2. A bag filler comprising a hopper having a discharge opening, material discharging means having a portion constructed of compressible material connected to said'o-pening, tongs in pivotal connection with said hopper for gripping said compressible portion tocheck the flow of material therefrom, and counter-weighted lever means in pivotal connection with said hopper for operating said tongs.

3. A. bag filler comprising material discharging means having a portion constructed of compressible material tongs in connection therewith for gripping said compressible portion to check the flow of material therefrom, a U-shaped lever pivoted to the material discharging means, and links connecting said lever with said tongs. I

L. A bag filler comprising material discharging means havin a portion constructed ofcompressible material, a pair of tongs on each side of the material discharging means, each pair being pivoted together at their inner ends and to the material discharging means, a channel strip secured to the outer ends of two opposed tongs adja'cent'one side of the tubular compressible member, a T' strip secured to the outer ends of the other two tongs adjacent the other side of the tubular compressible member, a U-shaped lever pivoted at its inner ends to the material discharging means, links pivotally connecting each inner end of the lever with the tongs, and a counterweight within the curved portion of the lever. I

5. A bag filler comprising a hopper having a lower opening therein, a tubular discharge member connected to said opening, a

' tubular member of compressible material connected to the lower end of the discharge member, a pair of tongs on each side of the discharge member, each pair being pivoted together at their inner endsand to the discharge member, a channel strip secured to the outer ends of two opposed tongs adjacent one side: of the tubular compressible member, a T-strip secured to the outer ends of the. other two tongs adjacent the other side of the tubular compressible member, a U-shaped lever pivoted at its inner ends to the material discharging means, links pivotallyconnecting each inner end of the lever with the tongs,

and a counterweight within the curved portion of the lever.

6. A receptacle filler comprising a hopper having a discharge opening, material discharging means having a portion constructed of compressible material connected to said opening, a pair of tongs pivoted to each side of the hopper, and engaging means connecting the lower ends of the opposed tongs for gripping the compressible portion therebetween to check the flow of material.

7. A receptacle filler comprising material discharging means having a portion constructed of compressible material, tongs in connection therewith for gripping said compressible portion to check the flow of material therefrom, a U-shaped lever pivoted to the material discharging means, links connecting said lever with said tongs, and a counterweight within the curved portion of the lever;

8. A receptacle. filler comprising a hopper having a discharge opening, material discharging means having a portion constructed of compressible material connected to said opening, a lever pivoted to each side ofsaid hopper for directly engaging said compressible means, and other means in connection with said hopper for operating said pivoted levers.

9. A bag filler comprising a hopper having a discharge opening, material discharging means having a portion constructed of compressible material connected to said opening, means pivotally connected to said hopper and engageable withsaid compressible portion for checking the flow of material therefrom, and other means in connection with said hopper for operating said compressible portion engaging means.

In testimony whereof, I afiix my signature.
